今天,24小时不间歇的网络运作对于许多机构来说,已经成为司空见惯的事情了。这就意味着没有什么意外的停机时间了。幸运的是,已经有一些产品可以为这些网络提供容错的措施。我们测试过的这些产品,可以通过保存重要文件拷贝的方法把停机时间降到最低的限度。每一种产品都采用了不同的机制,以满足高可用性计算的需要,总体来说,它们都改进了网络的可靠性。 Horizons Technology公司的LANshadow采用了定时拷贝文件的方法,适合于律师事务所等涉及许许多多小文件的应用场合。Vinca公司的StandbyServer 32提供了磁盘镜象功能,而Netguard Today, 24-hour non-stop network operations have become commonplace to many organizations. This means there is no unexpected downtime. Fortunately, there are already some products that can provide fault tolerance for these networks. The products that we have tested minimize downtime by saving copies of important files. Each of these products uses different mechanisms to meet the needs of high-availability computing, and they generally improve the reliability of the network. Horizons Technology’s LANshadow uses a method of timed-copying files, suitable for applications involving many small files such as law firms. Vinca’s StandbyServer 32 provides disk mirroring capabilities, while Netguard
